A Styrofoam cooler is good for more than keeping brewskies cold. Transform it into a real cooler by adding two dryer vents and small fan, essentially creating a DIY AC for less than 10 bucks. Carefully trace the circumference of the fan on the center of the cooler's cover, then trace the dryer vent openings on either side. Cut along the lines, vacuum up any stray bits of foam, and insert the vents and fan (blower side down) into the openings. Next, fill plastic bottles with water, freeze them until solid, then place them in the cooler. Finally, replace the cover, plug in the fan, and enjoy the breeze.
